FEATURISATION & MODEL TUNING¶

• DOMAIN: Semiconductor manufacturing process¶

• CONTEXT: A complex modern semiconductor manufacturing process is normally under constant surveillance via the monitoring of signals/variables collected from sensors and or process measurement points. However, not all of these signals are equally valuable in a specific monitoring system. The measured signals contain a combination of useful information, irrelevant information as well as noise. Engineers typically have a much larger number of signals than are actually required. If we consider each type of signal as a feature, then feature selection may be applied to identify the most relevant signals. The Process Engineers may then use these signals to determine key factors contributing to yield excursions downstream in the process. This will enable an increase in process throughput, decreased time to learning and reduce the per unit production costs. These signals can be used as features to predict the yield type. And by analysing and trying out different combinations of features, essential signals that are impacting the yield type can be identified.¶

• DATA DESCRIPTION: signal-data.csv : (1567, 592)¶

The data consists of 1567 datapoints each with 591 features. The dataset presented in this case represents a selection of such features where each example represents a single production entity with associated measured features and the labels represent a simple pass/fail yield for in house line testing. Target column “ –1” corresponds to a pass and “1” corresponds to a fail and the data time stamp is for that specific test point.

• PROJECT OBJECTIVE: We will build a classifier to predict the Pass/Fail yield of a particular process entity and analyse whether all the features are required to build the model or not.¶

Name: Pass/Fail, dtype: int64

Observations¶

  • The "Time" Column represet the time at which the signal was generated and seems to have very little impact on the model performace, Hence this can be Deleted
  • The values in 'Pass/Fail' is highly skewed where "Pass" represented by "-1" occupies "93%" and "fail" represented by "1" is around 6.5%
  • There are around 591 features which could be redundent and dimesions can be reduced using PCA
  • We can observe multiple columns with counts less than 1562 which represents missing data in the columns
  • 2. Data cleansing:¶

    2.A. Write a for loop which will remove all the features with 20%+ Null values and impute rest with mean of the feature¶

    In [15]:
    signal_df.isnull().sum().sum()
    
    Out[15]:
    41951
    In [16]:
    signal_df = signal_df.drop('Time', axis=1)
    for col in signal_df.columns:
        if signal_df[col].isnull().sum() / len(signal_df) >= 0.2:
            print(col)
            signal_df.drop(col, axis=1, inplace=True)
        else:
            signal_df[col].fillna(signal_df[col].mean(), inplace=True)

    Observations¶

  • As we can see after droping the features with 20%+ Null values around 33 features have been dropped.
  • as mentioned earlier the Time feature which is of object datatype has been dropped
  • 2.B. Identify and drop the features which are having same value for all the rows.¶

    In [19]:
    # Here we are using the nunique fucntion to identify the number of unique values in the columns.
    #The columns which has only one Unique value is being dropped
    nunique = signal_df.nunique()
    cols_to_drop = nunique[nunique == 1].index
    signal_df.drop(cols_to_drop, axis=1,inplace=True)
    print(signal_df.shape)
    
    (1567, 443)
    

    2.C. Drop other features if required using relevant functional knowledge. Clearly justify the same¶

  • As mentioned earlier the Time feature which is of object datatype has been dropped since it has very little impact on the model performance
  • Checking for columns with low variance and dropping the columns with variance less than "<0.1" .
  • In [20]:
    signal_var = signal_df.drop('Pass/Fail', 1).var().round(2)
    low_var_features = signal_var[signal_var <= 0.1]

    Observations¶

  • We have dropped around 188 features having variance less than "0.1" which will help in avoiding overfitting of the model
  • 2.D. Check for multi-collinearity in the data and take necessary action¶

    10 rows × 160 columns

    Observations¶

  • We have dropped around 95 features having corelation greater than .9 which is industry standard
  • Currently we have 160 features out of 592 features
  • 2.E. Make all relevant modifications on the data using both functional/logical reasoning/assumptions¶

  • We can check for the Columns having highly skewed data which will have minimum impact on the model prediction

     1    0.066369
    Name: Pass/Fail, dtype: float64

    Observations¶

    Univariate analysis of all the predictors features:

  • We can observe that the data in many features are either positively or negetively Skewed which can be treated using PCA
  • Univariate analysis of all the Target features:

  • Target feature is highly imbalanced where "-1" representing "Pass" having 93.3% and "Fail" having 6.6%
  • Outlier analysis using boxplot¶

    In [35]:
    plt.figure(figsize=(20, 50))
    col = 1
    for i in signal_new.columns:
        plt.subplot(56,10, col)
        sns.boxplot(signal_new[i],color='blue',orient='h')
        col += 1
    
    Observations:¶
  • We can observe that there are outliers in majority of the features
  • considering the volume of the outliers treating the outliers could cause information loss
  • 3.B. Perform bivariate and multivariate analysis with appropriate detailed comments after each analysis.¶

    In [36]:
    sns.pairplot(signal_new.iloc[:,0:15]);
    
    In [37]:
    sns.pairplot(signal_new.iloc[:,16:30]);

    plt.title('Correlation heatmap for the Data', fontsize = 20)
    
    Out[38]:
    Text(0.5, 1.0, 'Correlation heatmap for the Data')

    Observations¶

    multivariate analysis :

  • As we can observe from the above dist plot and the heat map, the data in majority of the features have minimum corelation.
  • Although some of the columns are still either positively or negetively corelated. This can be handled using PCA.
  • 4. Data pre-processing¶

    Observation:¶

  • From the above we can conclude that best parameters determined using Gridsearch CV results in best model with 88% accurecy on the test data
  • 5.D. Use any other technique/method which can enhance the model performance.¶

    Hint: Dimensionality reduction, attribute removal, standardisation/normalisation, target balancing etc.

    6.B. Select the final best trained model along with your detailed comments for selecting this model.¶

    Observations:¶
  • from the above we can conclude that the train and test accuracy for both SVM and Random Forest is ~100%.
  • however when we look at the Reacall and Precision,Since the requirement here is to reduce type 2 error ie.those production entities which actually failed, but we predict them as pass, we need to focus more on the Recall value than the precion
  • Considering the above we can select SVM model as the best trained model with "100%" recall and having F1 score of 99.6
  • 6.C.Pickle the selected model for future use¶

    6.D. Write your conclusion on the results¶

    Observation:¶

  • The Data set has around 592 features and suffers from the curse of dimesionality
  • The Original data has been treated for missing values,columns with only zero variance and low variance.
  • There were outliers in the data however was not treated since the same could have caused information loss
  • The target variable was highly imbalanced and was balanced using SMOT oversampling
  • PCA was used to reduce the dimentions of the data
  • Out of all the models built and trained SVM was the best trained model and had high recall, accuracy and F1 score
